4.7 Auto-Tuning
◆ Types of Auto-Tuning
The drive offers different types of Auto-Tuning for induction motors and permanent magnet motors. The type of Auto-
Tuning used differs further based on the control mode and other operating conditions. Refer to the tables below to select
the type of Auto-Tuning that bests suits the application. Directions on how to execute Auto-Tuning are listed in Start-Up
Flowcharts on page 107.
Note: The drive will only show Auto-Tuning parameters that are valid for the control mode that has been set to A1-02. If the control
mode is for an induction motor, the Auto-Tuning parameters for PM motors will not be available. If the control mode is for a PM
motor, the Auto-Tuning parameters for induction motors will not be available.
■ Auto-Tuning for Induction Motors of V/f control
This feature automatically sets the V/f pattern and motor parameters E1- and E2- for an induction motor.
Table 4.13 Types of Auto-Tuning for Induction Motors of V/f control
Table 4.14 lists the data that must be entered for Auto-Tuning. Make sure this data is available before starting Auto-
Tuning. The information needed is usually listed on the motor nameplate or in the motor test report provided by the
motor manufacturer. Also refer to page 108 and 109 for details on Auto-Tuning process and selections.
Table 4.14 Auto-Tuning Input Data
■ Auto-Tuning for Permanent Magnet Motors of OLV control
Automatically sets the V/f pattern and motor parameters E1- and E5- when a PM motor is used.
Table 4.15 Types of Auto-Tuning for Permanent Magnet Motors of OLV control
Table 4.16 lists the data that must be entered for Auto-Tuning. Make sure the data is available before starting Auto-
Tuning. The information needed is usually listed on the motor nameplate or in the motor test report provided by the
motor manufacturer. Also refer to page 109 for details on the tuning mode selection and the tuning process.
Type Setting Application Conditions and Benefits
Stationary Auto-Tuning for Line-to-Line
Resistance
T1-01 = 2
• The drive is used in V/f Control and other Auto-Tuning selections not possible.
• Drive and motor capacities differ.
• Tunes the drive after the cable between the drive and motor has been replaced with a cable over 50 m long.
Assumes Auto-Tuning has already been performed.
Rotational Auto-Tuning for V/f Control
T1-01 = 3
• Recommended for applications using Speed Estimation Speed Search or using the Energy Saving function
in V/f Control.
• Assumes motor can rotate while Auto-Tuning is executed. Increases accuracy for certain functions like
torque compensation, slip compensation, Energy Saving, and Speed Search.

Type Setting Application Conditions and Benefits
PM Motor Parameter Settings
T2-01 = 0
• Motor does not rotate during Auto-Tuning
• Motor test report or motor data like listed in Table 4.16 are available.
PM Stationary Auto-Tuning
T2-01 = 1
• A motor test report listing motor data is not available. Drive automatically calculates and sets motor
parameters.
PM Stationary Auto-Tuning for Stator
Resistance
T2-01 = 2
• Useful to tune the drive when the motor data were set up manually or by motor code and the cable is longer
than 50 m. Should also be performed if the cable has changed after earlier tuning.
